NPP1, a Phytophthora‐associated trigger of plant defense in parsley and Arabidopsis

Summary Activation of non‐cultivar‐specific plant defense against attempted microbial infection is mediated through the recognition of pathogen‐derived elicitors. Previously, we have identified a peptide fragment (Pep‐13) within a 42‐kDa cell wall transglutaminase from various Phytophthora species that triggers a multifacetted defense response in parsley cells. Many of these oomycete species have now been shown to possess another cell wall...
